본 발명은 오일쿨러에 관한 것으로서, 보다 상세하게는 라디에이터의 탱크에 내장되는 오일쿨러에 관한 것이다.The present invention relates to an oil cooler, and more particularly, to an oil cooler embedded in a tank of a radiator.

일반적으로 자동변속 차량에 있어서, 오일쿨러는 토크 컨버터나 동력전달 계통의 엔진오일을 냉각시키는 것으로 라디에이터의 탱크에 내장되어 엔진 냉각수를 이용하여 냉각하도록 하고 있다. In general, in an automatic transmission vehicle, an oil cooler cools engine oil of a torque converter or a power transmission system, and is mounted in a tank of a radiator to cool using engine coolant.

도1에 도시한 바와 같이, 종래 라디에이터의 탱크에 내장되는 오일쿨러(1)는 이중관으로 된 본체(2)와, 본체의 양측 외벽에 설치된 유입관(4)과 유출관(6)이 설치된 구조로서, 상기 본체(2)는 도2에 도시한 바와 같이 횡단면이 원형인 외관(8) 및 내관(10)과, 이 외관(8)과 내관(10) 사이에 오일의 냉각효율을 높이기 위한 전열핀(12)이 배치된 구조이다. As shown in Fig. 1, the oil cooler 1 incorporated in a tank of a conventional radiator has a structure in which a main body 2 formed of a double tube and an inlet tube 4 and an outlet tube 6 provided on both outer walls of the main body are installed. As shown in Fig. 2, the main body 2 has an outer appearance 8 and an inner tube 10 having a circular cross section, and heat transfer for increasing the cooling efficiency of the oil between the outer appearance 8 and the inner tube 10. The pin 12 is arranged.

도2에 도시한 바와 같이, 상기 외관(8)에는 나사부(14a)를 가진 플랜지(14)가 결합되고, 상기 플랜지(14)에 유입관(4) 및 유출관(6)이 결합되어, 상기 외관(8)과 내관(10) 사이에 오일이 유입/유출하게 되어 있다. 상기 외관(8)의 외부와 내관(10)의 내부에는 냉각수가 흐르면서 상기 오일과 열교환하게 된다. 상기 전열핀(12)은 도3에 도시한 바와같이 다수의 코루게이트핀이 소정의 간격으로 접합하여 형성된 구조이다.As shown in FIG. 2, the flange 8 having the threaded portion 14a is coupled to the exterior 8, and the inlet pipe 4 and the outlet pipe 6 are coupled to the flange 14, Oil flows in and out between the exterior 8 and the inner tube 10.
